陈式太极拳竞赛套路演练动作节奏变化规律探析

通过文献资料法、调查访问法、实验法、录像观察法和逻辑分析法对陈式太极拳竞赛套路的演练节奏进行分析研究。研究认为,节奏鲜明体现了陈式太极拳独特的韵味。陈式太极拳竞赛套路从头到尾有快有慢、有高潮有舒缓、波浪式前进。套路中的每个动作组合、每个段落都是由刚柔相济的动作相互衬托、鲜明对比构成的。在研究动作的基础上,对如何准确掌握陈式太极拳竞赛套路演练过程的动作节奏变化规律提出几点建议。

美国学校调查运动兴起的原因探析

19世纪末20世纪初,美国处于重大的社会转型时期,伴随着社会转型,社会各领域产生了一系列的问题,为解决这些社会问题,美国兴起了社会调查运动。受社会调查运动的影响,学校调查运动也开展起来,并成为社会调查运动的重要组成部分。在学校追求效率和教育寻求科学化的背景下,学校调查运动发展迅猛,对美国教育产生了重要影响。     

日本近代文学中的“言文一致”运动

对日本近代文学中的＂言文一致＂运动的研究可以分为两个阶段,第一阶段的研究是对其做出了高度评价,第二个阶段是在对日本明治时期的＂言文一致＂运动所进行的综合性研究的前提下所产生,并使之走下主流位置。对明治时期的＂言文一致＂运动以及日本近代文学的文体改革所具备的性质进行探讨可以清楚其走下主流位置的根本原因。     

东盟区域龙狮运动国际传播的伦理困境

东盟区域龙狮运动传播过程中伦理困境的解决是促进龙狮运动在国际上传播的重要影响因素。面对传播者的行为瓶颈问题,应从提高传播者的道德意识做起;面对传播媒介沦陷的问题,应注意龙狮运动传播媒介作用的正确发挥;面对中西方文化差异问题,应促进各国文化的融合;面对受众对龙狮运动的误解,应扩大对龙狮运动的正面宣传。深入解决龙狮运动传播的伦理困境,加快龙狮文化的国际传播脚步。

The load-velocity profile differs more between men and women than between individuals with different strength levels

This study aimed to determine the suitability of the load-velocity relationship to prescribe the relative load (%1RM) in women, as well as to compare the load-velocity profile between sexes and participants with different strength levels. The load-velocity relationship of 14 men (1RM: 1.17 ± 0.19) and 14 women (1RM: 0.66 ± 0.13) were evaluated in the bench press exercise. The main findings revealed that: (I) the load-velocity relationship was always strong and linear (R² range: 0.987–0.993), (II) a steeper load-velocity profile was observed in men compared to women (Effect size [ES]: 1.09), with men showing higher velocities for light loads (ES: ? 0.81 and ? 0.40 for the y-intercept and 30%1RM, respectively), but women reporting higher velocities for the heavy loads (ES: 1.14 and 1.50 at 90%1RM and 100%1RM, respectively); and (III) while the slope of the load-velocity profile was moderately steeper for weak men compared to their strong counterpart (ES: 1.02), small differences were observed between strong and weak women (ES: ? 0.39). While these results support the use of the individual load-velocity relationship to prescribe the %1RM in the bench press exercise for women, they also highlight the large disparities in their load-velocity profile compared to men.     

Improved children’s motor learning of the basketball free shooting pattern by associating subjective error estimation and extrinsic feedback

This study aimed at assessing the interaction between subjective error estimation and frequency of extrinsic feedback in the learning of the basketball free shooting pattern by children. 10- to 12-year olds were assigned to 1 of 4 groups combining subjective error estimation and relative frequency of extrinsic feedback (33% × 100%). Analysis of performance was based on quality of movement pattern. Analysis showed superior learning of the group combining error estimation and 100% feedback frequency, both groups receiving feedback on 33% of trials achieved intermediate results, and the group combining no requirement of error estimation and 100% feedback frequency had the poorest learning. Our results show the benefit of subjective error estimation in association with high frequency of extrinsic feedback in children’s motor learning of a sport motor pattern.     

Effect of Active Lessons on Physical Activity,Academic, and Health Outcomes: A Systematic Review

Purpose: The purpose of this study was to conduct a systematic review of classroom-based physical activity interventions that integrate academic content and assess the effectiveness of the interventions on physical activity, learning, facilitators of learning, and health outcomes. Method: Six electronic databases (ERIC, PubMed, Google Scholar, Science Direct, Cochrane Library, and EMBASE) and reference lists were searched for English-language articles, published January 1990 through March 2015, reporting classroom-based interventions that deliberately taught academic content using physically active teaching methods for at least 1 week duration, with physical activity, health, learning, or facilitators-of-learning outcomes. Two authors reviewed full-text articles. Data were extracted onto an Excel spreadsheet, and authors were contacted to confirm accuracy of the information presented. Results: Fifteen studies met the inclusion criteria. Six studies reporting on physical activity levels were found to have medium-to-large effect sizes. All 4 studies reporting learning outcomes showed positive effects of intervention lessons. Teachers and students were pleased with the programs, and enhanced on-task behavior was identified (n = 3). Positive effects were also reported on students’ body mass index levels (n = 3). Conclusions: Physically active academic lessons increase physical activity levels and may benefit learning and health outcomes. Both students and teachers positively received and enjoyed these teaching methods. These findings emphasize the need for such interventions to contribute toward public health policy.     

Political failure and the necessity for global democracy

Abstract

This paper aims to explore the changes in creative activities of young people – especially in the alternative media – in Indonesia before and after Reformasi. It begins with the story of the dynamics of a student press, from my personal experience – which I believe is a typical form of student/youth movement in Indonesia – and how the student’s life obviously depends on the political situation, the university policy, and the dynamics of the student’s life at that particular time. Reformasi caused political change and freedom but simultaneously, and ironically, placed the student press in a state of meaninglessness, such that it was painfully forced for search for new meanings to keep it contextually relevant in the new era. I end the paper describing the latest form of the alternative media scene of Indonesian youth, whose focus is dramatically shifting from ‘big’ political issues to issues of the celebration of communities and self‐existence.
